The olivine-type iron lithium phosphate, due to the anode material for lithium-ion batteries that cycle performance is excellent, safety performance is good, cheap, the starting material wide material sources are considered to have most DEVELOPMENT PROSPECT and potentiality, is one of lithium ion battery material that research is the most popular at present, industrialization is maximum.
The starting material selection of producing iron lithium phosphate is more extensive, and the production equipment system matched with it also has larger difference because of the selection of raw material.Adopting Ferrox, Quilonum Retard and primary ammonium phosphate is raw material or to adopt tertiary iron phosphate and Quilonum Retard be raw material, is generally high temperature solid-state method, uses liquid phase ball milling, vacuum drying process, then high-temperature roasting; Adopting ferrous sulfate, lithium hydroxide, phosphoric acid or ammonium phosphate is raw material, is generally liquid phase method or hydrothermal method, uses the synthetic presoma of hydrothermal reaction kettle of liquid phase reaction still or High Temperature High Pressure, low-temperature heat treatment then, then carry out the high-temperature roasting of short period of time.
But above-mentioned adopted raw material and production technique, whole manufacturing process is longer, and cost of raw and processed materials and production cost are all higher, are unfavorable for reducing production cost and the extensive industrialization of LiFePO 4 material.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and complete production system that the ferric phosphate lithium cell material that a kind of cost is low, equipment is simple is provided.
The purpose of this utility model can reach by following measure: a kind of complete production system of ferric phosphate lithium cell material; it is characterized in that comprising header tank 1, header tank 2 jointly by pipeline access reactor 3, reactor 3 connects spray-drying tower 4 by pipeline, and the inert atmosphere protection tunnel like stoving oven 5, ultrafine crusher 6, the vibratory screening apparatus 7 that connect successively and revolve the electromagnetic drying machine 8 that shakes and form.
In order further to realize the purpose of this utility model, the bottom of described header tank 1 and header tank 2 is higher than reactor 3 upper surfaces.
It is raw material that this complete production system adopts phosphoric acid solution, lithium hydroxide solution, ferric oxide, doped element, organic carbon source; through mixing in reactor; form the slurry containing ferric oxide, phosphate radical, lithium ion and dopant ion, organic carbon source; in spraying drying, rapid drying forms presoma; in the inert atmosphere protection high-temperature roasting; through pulverizing, sieving, dewater, form the ferric phosphate lithium cell material again.
The utility model can produce following positively effect compared with the prior art: native system equipment is simple and easy to get, and production capacity coordinates balanced, simple with the production technique of coordinative composition of equipments, the starting material cheapness that is easy to get, and the excellent product performance of production, belong to clean-production system.
